PPE Diesel GM Allison 2001-2007 Transfer Case Brace – PPE 129020107



Product Highlights:

Cracked transmission tail shaft housings (located between the transfer case and the transmission) are a common problem for GM Allison-equipped 4×4 pick-ups in off-road and drag racing applications.

Even a nominal amount of driveline vibration can cause the housing to fail, resulting in a transmission fluid leak or worse; internal transmission and transfer case damage. Once the housing cracks, repairing it requires removal of the transmission and transfer case.

>PPEs new Transmission Transfer Case Brace helps support the overhanging, heavy transfer case by spreading the load up and across the adaptor housing to the center section of the transmission.

>PPEs Transmission Transfer Case Brace utilizes two 304 stainless-steel 7/8 inch support tubes tied together with a thick 304 stainless-steel plate for increased strength and service life.

Mounting the brace is a quick and easy job that can be done without removal of the transmission or transfer case. No special tools required.
